MICHAEL E. RUDASILL, OF SHELBY, NORTH CAROLINA.

PUMP.

Specification of Letters Patent No. 30,354, dated October 9, 1860.

T o all whom t may concern.'

Be it known that I, M. E. RUDAsILL, of Shelby, in the county ofCleveland and State of North Carolina, have invented certain new anduseful Improvements in Pumps; and Il do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings and to the letters of referencemarked thereon.

The nature of my invention consists in constructing and arranging theseveral parts of this pump in the manner hereinafter specified.

In the annexed drawings Figure l represents a side elevation. Fig. 2 isa vertical section.

In the figures A, represents a wooden or metallic plate upon which thecylinders are secured. Passing up from the ends of this plate are twosupports, which are connected as shown at their tops by means of acrosspieoe a, through which the pump shaft passes.

To the under side of the plate A, is secured a water box C, which ismade in a strong and substantial manner.

B, B, represent two cylinders which are placed and secured upon the topof plate A. These cylinders are hollow, as repre sented, and areprovided with hollow pistons which work in them the pistons are markedI, I, and each one of them is provided with two rods or vertical bars Gand H;

F, F, represent springs which connect the bars Gr, G, to the cross piecea, said springs serve to raise the pistons after they have beendepressed.

D, represents a vertical shaft which is made hollow and which passesdown between the cylinders and connects with and opens into the boX C.This shaft D, passes up to the top of the well and is provided at itsupper end with a crank handle. The shaft D, is also provided witha camcylinder E, which is made in the form and shape represented in thefigures. This cam serves to operate the bars H, H, and as said bars areplaced on different sides of it they are moved alternately. As one ismoving down the other is moving up, the piston being drawn up by meansof the spring G. When the shaft D, revolves then, the two pistons I Iare moved up and down alternately by means of the cam and the springs F,F.

c, o, represent valves secured tothe bottom of the pistons and (Z, d,represent valves secured to the bottom of the plate A.

It will be readily seen that by this arrangement when the cylinders areimmersed in water the up and down movement of the pistons will cause thewater box C, to till' with water, and that the water will then be forcedup through the hollow shaft and out at the top of said shaft. I amenabled by this arrangement to throw a large stream of water withcomparatively little power.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent is- The arrangement of the plate A, box, C,and cylinders B, B, with the pistons I, I, springs F, F, hollow shaft D,and cam cylinder E, the several parts being connected and made tooperate substantially as and for the purpose herein speciiied.
